本文实例讲述了php实现singleton()单例模式的方法。分享给大家供大家参考。具体实现方法如下:
common.php文件如下:
class CC
{
private static $ins;
public static function singleton()
{
if (!isset(self::$ins)){
$c = __CLASS__;
self::$ins = new $c;
}
return self::$ins;
}
public function EventResult($Id)
{
return $Id;
}
}
?>
index.php文件如下:
测试
require 'common.php';
$objCC=CC::singleton();
$r=$objCC->EventResult(7);
print_r($objCC);
echo $r."";
?>
希望本文所述对大家的PHP程序设计有所帮助。
